And again, more conflict. :-?
Tank is 121 x 45 x 40 so it would fit in there.
Being 17 years old, I guess if I bought some small ones, by the time they reach a large size I would be leaving my house (maybe) or would have a job so would be able to buy a larger tank.
At 30cm long they would have enough room to swim their length 4 times in my tank, with enough room to turn and swim upwards.
Thanks for input so far, more please!
PS, un-protected light tubes in the hood of my tank, would this cause a problem?
